BINDER-LOCK.

Application filed March 28, 1913.

T0 alt w/wm t may concern Be it known that l, lILLmM GrFFoRD JoNns, a citizen of the United States, residing at Chicago, in the count-y of Cook and State of Illinois, have invented a new and useful Improvement in Binder-Looks, of which the following is a specification.

My invention relates particularly to looseleaf binder-locks of the type set forth in my Patent No. 816,915.

My primary object is to provide a lock of the type referred to of improved construction and operation.

The invention is illustrated in its preferred embodiment in the accompanying drawing, in which- Figure 1 represents a broken plan view of a binder-frame and lock co-acting therewith shown separated therefrom; Fig. 2, a broken longitudinal vertical section showing the lock connected with the binder; Fig. 3, an enlarged vertical sectional view of the improved lock with the bolt in the locking position; Fig. 4f, an enlarged broken transverse section taken as indicated at line 4: of Fig. 2; Fig. 5, an enlarged rear end view of the bolt-actuating key-barrel employed; and Fig. (-3, an enlarged front elevational view of the bolt.

The binder in connection with which the invention is, for convenience, illustrated, comprises a back A equipped with a screwrod A, which is provided at one end with an angled key-receiving shank 1, by means of which the rod may be actuated; a pair of clamping members B, B transversely slidable upon the back A and equipped with the usual extensible binding-posts B2; wedgeshaped followers B3 having screw connection with the rod A and slidable connection with the oblique guides 2 with which the clamping members are equipped; and flexible members B4 connected with the members B3 and with the clamping members and serving in the operation of Closing the clamping` members in a well known manner.

The shank portion 1 of the screw-rod A is housed beneath a. bridge member 3 having portions 3a which serve as transverse guides for the binder-frame. That is, the bridge portions 3a are separated from the inner surface of the back member A by spaces l, as shown in Fig. 4, which admit the inturned flanges 5 of the clamping members B, B', The bridge portions 3 are sepa- Specification of Letters Patent.

rated by a slot or space 6, beneath which the back A is provided with a longitudinal recess or concavity 6a intercepted n-ear its inner end by a bolt socket or cavity 7. The lock C comprises a casing S which is adapted to slide within the lock-receiving cavity of the binder-frame afforded by the slot G and concavity Ga, said casing comprising an approximately cylindrical lower portion 8a and an upward extension 8b of general rectangular form, but with slightly convergent sides, thus having the form of a keystone; a vertically disposed bolt 9 adapted to work in a vertical chamber 9a with which the casing 8 is provided at its rear portion, the chamberl SPL being` open at its lower end; a rotatable key-barrel 10 contained in the bore with which the lower portion 8 of the casing is provided, said bore intercepting the vertical bore 9a; and a series of barrel-locking plungers 11 adapted to be moved during the insertion of the key to release the barrel in the usual manner.

The barrel is provided with the usual longitudinal key-slot 12 which is provided with a ledge 12a adapted to support the balls associated with the barrel-locking` plungers 11. The rear end of the barrel 1() is equipped with an eccentrically mounted pin 13 which engages a transverse slot 13a in the front surface of the vertically disposed bolt 9.

The portion S" of the lock-casing serves to house the upper sections 11a of the tumblers or barrel-locking plunger-s. then the key 14 is inserted, the plunger sect-ions will separate on the line 11b, allowing the barrel to be turned to retract the bolt. ldlhen this action occurs, it will be noted that the lower sections of the pluugers will be locked within the bore which contains the barrel 10, so that the key will be locked within the barrel and will serve as a means for withdrawing the lock-casing from the binder-frame.

rlhe barrel 10 is provided near its front end with a circumferential groove 15 which intercepts the key-slot 12 and is adapted to engage an internal lug 1G with which the lock-casing is equipped near its front end. The key-barrel may be entered by aliniug the slot l2 with the lug 1G, and after partial rotatiou the key-barrel is locked in pcsition by the lug 16, as will be evident from F ig. 4.

It will be understood that after the binder has been adjusted to clamp the leaves 1'?,

the lock may be inserted and secured by turning the key vto the withdrawing position, after Which the key may be Withdrawn, leaving the lock secured in place. The removal of the lock may be effected in the ina-nner suggested above, after which a separate key may be employed for actuating the 'screw-rod A. N hen the lock-casing is in position, it is additionally secured by lateral shoulders 18 with which the portion 8a of the lock-casing is pro-vided, While the portion 8b of the lock-casing projects through the slot or space 6. After the bolt is retracted by means of the key 14, the lock may be Withdrawn by longitudinal movement. To prevent the bolt from turning in its guide, it is preferred to employ a transverse pin 19 Which engages a slot 19et With which the bolt is provided in its upper portion.

F rom the foregoing description it Will be understood that the improved lock is of simplied construction, and that its parts may be readily separated at will to facilitate inspection or repair. Also, the bolt 9 is adapted to have secure engagement With the socket 7 so that ythere is no danger of these parts Wearing to such extent as to jeopardize the eliiciency of the lock.

The foregoing detailed description has been given for clearness of understanding, and no undue limitation should be understood therefrom.

l/Vhat 1 regard as new and desire to secure by Letters Patent is- 1. The combination with an expansible binder-frame equipped With actuating means and provided With a lock-chamber having a bolt-socket associated therewith, of a removable lock comprising a lock-casing, a key-barrel extending thereinto, barrel-locking means connected with said loclocasing, a bolt in the rear portion of the lock-casing disposed at right angles to said barrel, and an eccentric pin carried by the inner end of said barrel and engaging a slot in said bolt.

2. The combination With an extensible binder -frame provided With actuating means, including a screw-rod having a leyengaging shank and a bridge-piece carried by the binder-frame and provided With a slo-t, of a removable lock comprising av lock-Y casing having lateral shoulde engaging the lower surface of said bridge-piece and having an upward extension extending through said slot, a bolt in said casing adapted to engage a socket With which the binderframe is equipped, a key-barrel in said lock casing, and actuating means for the bolt carried by said key-barrel. Y

3. The combination with a binder-frame comprising a back, transversely-slidable clamping members mounted thereon, and actuating means for said clamping members, including a screwerod, of a member carried by said back and spaced a short distance therefrom, said member provided With a long gitudinal. slot and said back provided with a concavity disposed beneath said slot, and a lock comprising a lock-casing having its lo-Wer portion fitting in said concavity and having also an upward extension projecting through said slot, said lock-casing having lateral shoulders disposed beneath the member carried by said back, a bolt in the lock-casing engaging a socket in said back, and a key-barrel in said lock-casing equipped With means for actuating said bolt.

4. A lock for the purpose set forth, comprising a lock-casing having its rear portion provided With a vertical bore and its front portion provided With a horizontal bore, a bolt in said vertical bore having its tro-nt portion provided With a slot, and a key-barrel in said horizontal bore having its rear end equipped with an eccentric pin engaging said slot.

5. A lock for the purpose set forth, co1nprising a lock-casing having its rear portion provided with a vertical bore and; its lower front portion provided with a horizontal bore, a bolt in said vertical bore, and a leybarrel in said horizontal bore equipped with means for actuating said bolt, said horizontal bore having an internal stud engaging a circumferential groove with Which said key-barrel is provided.
